Senturion XPR04 Proximity Probe

Quick Overview

The Senturion XPR04 proximity probe system is an 8mm tip proximity sensor that uses eddy current principle to measure distance up to 2.5mm or 4mm with resolution of less than 1 micrometer. It is designed for monitoring targets from as little as 16mm in applications, even those in a harsh environments (up to 180°C). The system includes a driver unit with a 5, 7, or 9m extension cable. The cable system incorporates snap lock connectors and double screened cable for easy installation and high immunity to interference.

The Senturion XPR04 proximity probe system is a type of proximity sensor that uses the eddy current principle to measure the distance between the probe and a target. The probe has a small, 8mm tip that is made of a conductive material. When the probe is brought close to the target, an eddy current is induced in the target material. The strength of the eddy current is proportional to the distance between the probe and the target. The driver unit converts the eddy current signal into a voltage output that is proportional to the distance.

The XPR04 proximity probe system is designed for tight installation applications. It has a range of up to 2.5mm and a nominal sensitivity of 7.87 mV/µm or 4mm with a sensitivity of 3.94 mV/µm. The system is also designed for harsh environments and can operate up to 180°C.


  • Switch selectable system cable lengths 5m, 7m and 9m.
  • 8mm tip diameter ensures a clear signal from the target material
  • LED indication of selected length.
  • 3.5mm socket for gap voltage monitoring.
  • Double screened cable for high noise immunity.
  • Snap lock and shake proof cable connection.
  • Excellent repeatability on replacement of probe, extension or driver.
  • Compliant with standard API 670.
